Fabric Developer Docs

The current public beta is one authenticated local cognition connector. It combines the continuously refreshed Indexer graph for one explicit project with governed Fractal memory, provenance, correction, and recall. A Cognisos account and browser sign-in are required; the credential remains in the OS keychain.

Reference

• Quickstart — install Fabric MCP in five minutes
• Fabric Indexer — the typed-knowledge-graph engine, what it indexes, performance
• MCP Overview — what the server gives your AI client
• MCP Tool Reference — full reference for all MCP tools

Integrations

• Claude Code — five-minute setup
• Cursor — per-repo or global MCP config

Hosted connectors

Two-way sync between Fabric and external systems — ingest content into the graph, emit back when Fabric writes.

• GitHub — GitHub App install with PR/issue/review ingestion, indexer-backed PR-summary comment, and /fabric slash commands
• Obsidian — local vault sync via filesystem watcher, no plugin install
• Slack — workspace messages, threads, and reactions; HTTP Events API or Socket Mode

Getting started

The fastest path is:

cd /path/to/your/project
npx -y @cognisos/fabric-mcp@beta-candidate setup

Then restart the client and verify one fabric connector exposes both fabric_* and fractal_* tools. The Fabric Code Indexer daemon is required; the separate Fractal background capture daemon is optional and off by default.
